ALBERT J. TAILIN, OF BLOOMINGTON, ILLINOIS.

IMPROVEMENT IN GRAlNlNG-ROLLERS.

Specification forming part of Letters Patent No. l6&,056, dated June 1,1875; application filed March 6, 1875:

To all whom it may concern Be it known that I, ALBERT J. TAPLIN, ofBloomington, in the county of McLean and in the State of Illinois, haveinvented certain new and useful Improvements in Graining- Machines; anddo hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof an adjustable or extension graining-machine, as will be hereinaftermore fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure l is a plan view of my machine. Fig. 2 is an end elevation of thesame, and Fig. 3 is a section through the line a: at, Fig. 1.

AArepresent two light portable iron wheels, connected by means offourright-and-left-hand screws, B B, passing through the spokes or radialarms of the wheel. These screws also pass through the ends of supportingor strengthening bars 0 O, which are attached to and kept in position bya center shaft, D, passing through the centers of said bars and throughthe centers of the wheels A A. These wheels revolve on the shaft D, andon the ends of the shaft are fastened or placed suitable handles E E. Bythis construction of the frame-work of my machine it can be easilyextended and contracted, or adjusted to the desired width correspondingwith the different objects and surfaces required to be grained, by meansof a suitable thumb-piece or key applied on the ends of theright-and-left-hand screws B B. On each end of the center shaft D isplaced a lever, G, the outer end of which forms a socket, a, and throughthese sockets passes a bar, I, having the handle J permanently attachedto it in the center, the bar I being adjusted according to the size ofthe wheel, and held in the sockets by means of set-screws b b. Thelevers G G are bent outward, as shown at H H, forming openings for thepassage of the ends of the screws B B when the wheel revolves, even whencontracted to the smallest possible size. The handle J is used forpropelling the machine, and the handles E E for guiding the machine andadapting it to work in a mechanical manner while in use, moreparticularly for grainin g objects and surfaces in a horizontalposition, such as lockrails for doors, coffins, furniture, or othersimilar manufactured goods. The outside surface or belting consists of acomposition, K, fastened on a canvas or other belt, L, passed. aroundand under the rims of thewheels A A, and fastened in the center on theinside.

The composition K is made in the following manner: Ten ounces pressed'flaxseed-oil is a heated to near the boiling-point in an iron vessel,when one ounce of chloride of sulphur is added, which readily dissolvestherein. Two pounds of best glue is dissolved by means of a water-bath,and eight ounces of glycerine added thereto, which are thoroughly mixedby stirring. The two preparations are then mixed together and wellstirred, after which, while yet warm, it is poured into molds fromone-eighth to one-quarter of an inch in thickness, more or less, and inlength and width to correspond with the belt desired.

If a smooth surface is required for transfer graining-belts the moldsare made of sheetiron; but if the impression or the figure of the grainis required to be permanently fixed in order to grain from the belt tothe object or surface, the figure of the grain in the desired wood mustbe made to rise or stand out by a successive steaming and dryingprocess. This is readily done by having the piece of desired wood placedin a steam-chest for about 7 one or two hours, then bringing it out ofthe steam-chest and placing it before a hot fur-.

nace, or in a drying-kiln or other position, where it will dry rapidly,repeating this operation two or three times, according to the hardnessor solidity of the wood. By this process the figure of the grain in thewood is made to stand out in such a manner that the composition K, beingmolded thereon, will have the permanent impression or figure of thegrain in the wood molded from one-eighth to threesixteenths of an inchin depth, and exactly corresponding with the grain in the wood.

Whilethe composition is yet warm and in the mold wooden laths (l d arepressed into the composition at suitable intervals. The laths (Z arethus permanently fastened to the composition K, and keep the compositionto an even surface while on the graining-machine. The canvas belt L isthen fastened to the slats, and the edges thereof cut to form triangularflaps, which fold over and under the rims of the wheels A A, and arefastened together by eyelets e e, or other suitable fastening.

When the belting is thus fastened the machine is easily adjusted bymeans of the extension-screws B B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a graining-machine, the combination of the adjustable wheels A A,right-and-lefthand adjusting-screws B B, center shaft D, andsupporting-arms O O, substantially as and for the purposes herein setforth.

2. The combination of the adjustable frame, composed of wheels'andscrews A B, with center shaft D, levers G G with bends H H and sockets-aa, the sliding bar I with handle J, and the set-screws b b, allsubstantially as and for the purposes herein set forth.

3. In a graining-machine, the outside belting, consisting of thecomposition K, slats d d, and canvas or other belt L, arranged upon anadjustable frame, substantially as and for the purposes herein setforth.

In testimony that Ielaim the foregoing I have hereunto set my hand this30th day of J anuary, 1875.

ALBERT J. TAPLIN.
